    Default Sick plant - Help Needed! (New growth stunted and pale yellow)

    I have a couple of RQS Bubble Kush in Aquafarms 4 weeks into Veg, each under 2x 600w HPS, using Dutch pro running EC 1.2-1.3 and PH ranging from 5.2-6.2, Temps 28-30c ( I like to vary it through out the weak to avoid lockouts for prolonged periods. I have another 3 Critical in Waterfarms who are thriving, but the new growth seems to be stunted and pale yellow. Anyone have any ideas. The water is shit where I am in Spain so use a water filtration system.

    It would be my guess your girl is suffering from a nutrient lock out which is creating a deficiency. I have no experience with hydro, so it is only a guess

    Ok mate, that size plant should be thriving from 1.2 ec. but whats the background ec mate? how much are you actually feeding. Why is water shit? You are filtering yeah with a r o system? If so then how are you supplementing your micro elements i.e cal, mag, iron etc etc? some base nutes have a bit in but generally they are formulated in countries where there is rock salts in the water, so its more a top up. if youre stripping your water of elements then you need to replace them cal, mag would be a good start.

    Anyway that aside those plant stressed from heat 1 lamp is adequate mate, your burning an extra lamp for nothing. When its 3 times the size and full of donkey dicks then yes 2 lamps. All it doing is reducing your yield buddy. What up with the balc any way? lucky bugger spain grr mumble spit, grr, not fair
