wtf is happening here ??

[voodo ray]

122993hi all need some advice my plants are in the 4th week of flowering,i have six plants growing three are fine, the other 3 the leaves have started to go paler in places mainly at the top of the plants also the buds arent really forming like the others,been looking on here to find the problem and think it might be a phosphorous issue,i think i have over fed them aswell so not sure if its to much or to little phosphorous any advice would be great thanks 122989122990122991122992

My 1st call would be to check for bugs, thrips, spider mite and so forth, Rule out the easy part 1st, Im sure phosphorous issues show up dark on the leaves, which leads me to think otherwise ?

[voodo ray]

thanks for the quick reply one of the plants went really green so i flushed it that was last week cut the nutes by half for all of them for three days have now upped the nutes again an thought that was the prob so im going to look for bugs right now.....

How longs it been like that?

[Budmore]

Have you had a good gander under leaves & in the dirt for bugs??

Could do with some closer pics of the damage.

Here, Found this for you, Its not always easy to find info on THC well I struggle as im shit with computers.

Thrips are tiny, 1/5"(5 mm) long, seen as animated lines running along veins on the undersides of plant leaves. Often, their signs of damage, (leaves infested with thrips will appear brown or a mottled silver and dried rather than wilted) are more evident than sight of the thrips themselves. Their fecal spots may appear as black sooty spots.

Blue sticky traps have been proven effective to detect thrips in greenhouse crops, hung so that the top of the trap lies in a zone of 2 feet (61 cm) above the plants, with the bottom within an inch (25 mm) of the highest leaves. Control is most effective when beneficial insects are released as soon as thrips are noted on the sticky trap.

Physical Control of Thrips - Moisture Control:

Studies have shown that dry plants, or plants lacking sufficient moisture are most likely to suffer attack by thrips, so adequate water placement by irrigation and mulching can be the first defense in controlling thrips.

Physical Control of Thrips - Let the Weed Border Grow:

Many thrip species thrive on weed vegetation so destroying or removing their natural habitat can cause them to move onto the cultivated plants.

Physical Control of Thrips - Mulch with Foil or Newspaper:

Shiny aluminum foil used as mulch around the base of plants disorients the egg-laying of thrips while any type of mulch that prevents weed growth does double duty in suppressing the emergence of thrip pupae from the soil.

Biological Control of Thrips:

Predatory mites and Lacewing larvae are commercially available and are suitable for release onto indoor plants. However, the lacewing larvae will need to be captured by hand or gently vacuumed up and released outdoors when they mature into flying adults. In addition, predatory nematodes control most thrip species and research is ongoing to develop airborne transmission methods for nematodes dispersal. Last but not least, Pirate and Damsel Bugs are natural predators of thrips as well as numerous other insects and can be encouraged to visit the garden by plantings of alfalfa, goldenrod and yarrow.

Chemical Control of Thrips Using Least-toxic Treatments:

Thrips have been shown to develop resistance to most insecticides used on a regular basis,yet least-toxic options like insecticidal soaps and horticultural oils can aid the gardener with thrip control until beneficial insect populations are thriving or supplemented.

just had a good look cant see no bugs or sfa in there cant take any more pics the bulbs on,the one that had it first has stopped growing and the top side branches have over taken the top of the plant,it looks like shit is shit load of shit,will take more pics tomoz an GERALD is a good friend of mine lol

[Mr-Lover]

Thats Them Little Bugger Bugs, i Am Having the Same Problem With my Outdoor Plants..

never seen them before, no wonder there small as,how have you been trying to get rid of them ???

[jason79]

sorry but thrips do not eat leaves (pic 1)

and thrips start at the base of the plant not the top

does it only affect the top of the plant if so

did you spray the plants with the lights on and burn the leaves ?

[Mr-Lover]

Yeah They Are, My Sister told me Yesterday She See a Little Bird Pecking at My Leafs Aswell, i Have Found Little White Bugs on Her, i Check Her Daily Now When She Outside Bring Her in over Night.. Have you Seen Any little White Spider Looking Thing on your plants? Will Try Find One on Her and Get a Picture When i Bring Her in to Update Diary..

no never sprayed them i did think it was to much phosphorous as the buds werent growing on one of the plants then they went brown so had a search on here an thats where i got the idea it was that,i flushed the plant hoping it would be ok then seen two more with the same thing an this is now where im at .........

i will try but there lots of thing it could be
whats the canopy temp

[voodo ray]

i will try but there lots of thing it could be
whats the canopy temp

its about 78 i have a aircooled hood,thing is i have 6 plants 5 nl an a dinafem cheese,3 of them are looking good two nl +the cheese,the others are a bit smaller an there the ones showing the problems as its only on the new leaves coming through which are getting smaller but showing more of it as they flower more.....

[jason79]

so the temps are not the cause of this but if it affecting new growth and has spread to other plants, it could Tobacco Mosaic Virus
keep the healthy plants away from the other ones and try to find out if it is or not with pic's on Google
