Hi All, been growing for about 18 months,
first 2 batches were "auto's" done in soil, the third batch more auto's, but done in a hydroponic rig, and now on my 4th batch, non-auto feminized seeds also in the hydroponic rig.
During all the growing I have done, the vegetative state showed good (if a little slow) growth with little to no problems, but I always hit problems when going into bloom.
The new leaves produced during the flowering stretch always seems to show symptoms of some sort of deficiency, but using the various trouble shooting guides I cannot identify the problem.
I have found that while the plants are very tolerant of nutrient levels during the vegetative state, the moment the stretch begins with the bloom lights on and 12/12 hour light cycle, the plants become extremely sensitive to the nutrient levels. It seems like just one drop of nutrient too much and they turn into wilting drama queens.
The new leaves are very pale green almost yellowish at the new growth point, and/or looking pale between the veins - this is all on the new growth during the flowering stretch - non of the other leaves show any signs of problems.
This discolouration during the flowering stretch occurs every time, but for this last batch, it does seem to be worse and I don't want to lose this crop after putting so much effort in.
i use municipal water, so hoping that there should be plenty of dissolved minerals, such as Ca, Mg, Fe & Zn
And I use the General Hydroponics formulas and very strict about adding the exact amounts for the growing phase. The only change was to use the "general Hydroponics - Micro" for Hard water, whereas the prior grows was with the regular formula.
First two photos are from the canopy of "Jack Herrer",
while the third is a closeup of "Amnesia Haze" - here you can see the pale green is between the veins.
Any help or advice would be appreciated...
