First time grow problem 1

[Tommy_420]

Hello fellow growers just a few pictures to see if this is just a noob mistake or something more....
Everything was growing really well a week ago then problems started to arise,
growing in plain fruit and flower compost.
600HPS 12/12 light.
7 litre soil pots
feed has been 1 Litre per plant a day with a little run off and plenty of soil moisture. (next day emptied and re watered)
Room temp is 24.C Dark, 28.C daylight.
Extract fan comes on for 10 minuites every hour, 4 hours extract a day (slight smell but nothing overpowering)
constant intake on low with extra boost if needed, room feels like its taking off with boost on
No humidity reader/ph or ppm readers
Night cycle: 2 air cycle fans low setting (one blowing into the room from the dormant low intake vent (still draws plenty of fresh air) and another cycling the room air mid/high height)
Day cycle: 2 air cycle fans one low, one medium (white oscillating fan in pictures on medium 2 setting, also low set fan over intake vent)
Chemicals i currently have: Ionic bloom 7ml per ltr /grow 7ml per ltr /PK boost 1ml per ltr : Canna PK 14/15 1.5ml per ltr : formulex 5ml per ltr (as stated on bottles)

everything was fine until my leaves started crisping like a tan brown not really falling off just crisping first 2 days wasnt to bad on the 3rd day my biggest looked like fungal feces , thinking something was wrong i stopped and flushed for 3 days so far (flush day 4 28th feb 2017) it seems to have stopped and not got any worse but the buds now smell dam and ive lost alot of green out of the plant, stem still looks healthy though, but its nice to hear from people who have more idea and have more knowledge, hope this is plenty of information, mybe to many ins and outs...
Thank you in advance Tommy

Are they sitting in their own run off, or is it just poor pics?

[Tommy_420]

yes they are poor pics but yes it is also there own run off. probably never more than 200-300ml run off. have a litre of feed a day but i empty the pans when the light comes on to give at-least a few hours of soil dry time for root oxygen, try to only feed and disturb once maybe twice in there daylight times, my worries were not to over water but there drinking water fine , just don't look fine. bud is still springy and firm but the edges and leaves are crisping, my light is just over 22" inch from my top bud, originally made the new growers mistake of moving my light up thinking it was heat and light burn, i also have mirrors under my plants to bounce the light around a little more ... wasn't sure if it helps but in my head it was logical... ha ha

You should remove the run off straight away. The mirrors will reflect the light causing hotspots so i would advise getting them out. Also your feeds seem really heavy but i have never used the nutes you are using so might be wrong.

Also watering every day.... make sure you let your plants have a good wet and dry cycle.. after watering and pot has drained properly, lift it and see the weight, then make sure it is reasonably lighter before watering again.... it really sounds like overwatering.
I only water every 4-5 days

If you can raise the pots an inch or 2 to get air circulating around and under your pots try and get a digital thermo can get them 99p eBay

If you're watering every day and leaving them in run off then you are most likely drowning your plants.

You should water with enough to create some run off and then remove run off and leave them for days until the soil is really dry.

Watering every day will do them no good at all mate.

You're also using two pk boosters from what I can tell which is a little pointless. Also as stated your feed seems strong so I'd say you also have nute burn and possibly salt build up.

I'd advise you flush them and then let them dry out for a good few days.

Ok, thank you all very much,
not sure if i can leave 2 of them that long without under-watering, they will easily have a litre in a day,
i will try not feeding for a few days, guaranteed they will be dry and empty of water by the time the light comes on today.
i also have some half inch pot stacks so i will put some under my pots for air circulation and lift higher from water, didn't realize run off was that bad, will stop doing that.
i did notice the PK boost from ionic is the same as the Canna PK 14/15 (currently not using either) ... dont seem to have any salt build up in or around my pans or pots

ive checked out some grow charts for ionic growing and it does say 7ml bloom per ltr even on the grow charts but the charts do say 5ml per ltr for grow (currently not using)... i do think its alot but then its 1 chemical unlike other brand names where i have to add 4-6 different things

Thanks you all for the reply's and answers any other information is greatly appreciated
