I amusing fox farm ocean forest cut with 25% perlite. They are in 5 gal grow pouches. I started feeding them with nutes when the first deficiencies appeared which turned put to be a small N def, that was at about week 5. They get around 3/4 a gal of water, I water till I start to get good runoff. As for the nutes I just divide what the schedule says by what strength I am using and sometime have to eyeball a little. I guess one reason I'm so low on strength is because I nute burned my male (before I knew it was male) and what I have been feeding seemed to be doing fine. Then these markings appeared probably a little over a week ago. The spray is a 1/2 tsp of mg per quart of water and I just added a drop to the soap to the spray bottle. I really am grateful for any knowledge
at 5 weeks 5 gallons of ocean forest should be still chock full of nitrogen, i suspect you've got root rot from over watering, ocean forest holds a good amount of moisture so unless youre watering every 3-4 days, your probably drowning em.
indoors, where the sun cant evaporate the water, and the plant grows slower and transpires less, you need to use less water.
dont give them any water for several days, until you see the top droop, then water deeply and note how much water the pot soaked up, and wait for the droop again and repeat. by keeping track of how much water they are actually using, youll probably discover youre giving them 2-3 times as much as they can actually use, and the rest just grows funk on the roots.
alternately, extract one of them from her pot and look at the soil at the bottom. it's most likely a slimy mess and your roots will be brown and stinky. the solution in that case is to repot in a larger container as follows:
1 ) in a large basin or even your bathtub, prepare a lukewarm water bath (~70 degrees, it must NOT be hot)
2 ) prepare the new larger pot by filling it 1/3 of the way with fresh soil mix
3 ) extract your plant from the pot and immerse the root ball in the warm water bath
4 ) massage the roots GENTLY until the contaminated soil washes free
5 ) plant her in the new pot, and fill in, it's ok to cover some stem which was previously exposed, that area will grow roots very rapidly
6 ) water her in, and then DO NOT WATER until the pot feels light, then do not water again until the pot feels light again. (a good tip is to keep an identical pot with just soil in it to compare weights)
7 ) after several weeks watch for the foliage getting pale, thats when youll want to add fertilizers, but not before.
