Hi could someone please tell me what is up with these plants?
They are 20 days from when they first broke soil and appeared above ground.
The second leaf set never grew in properly on all the plants, in effect they sort of self topped themselves. With new growth coming from the sideshoots instead.
Were started off in john innes no1 for first 2 weeks under 110w flourescent light.
Repotted into 11litre pots of john innes no2 at 2 weeks and placed under 400w hps for 4 days.
HPS was turned up to 600w 2 days ago.
Fed plain tap water.
Strains are barneys pineapple chunk and sin trabajo (both autoflowering)
Max temperature 78, minimum temperature at lights off 65
Plenty of airflow
Grew very successfully with 250w cfl in a closet for a few years with autoflowers using only miracle grow soil, no nutrients, and an oscillating fan as only ventilation. Usually grew 3 plants and got 3oz each time.
Took a break for a good while and tried again using proper equipment. First grow was 3 bagseed plants,they hermied and were chopped early. Got about 2 and a half oz
Second grow 6 feminised photoperiods using biocanna nutes and bioterra soil. Soil infested with fungus gnats. (from the bag) Great soil but really not impressed with the gnats in it. No reply from canna about their soil issues. Chopped early due to a number of plants hermieing and aphid infestation as well as gnats making roots sick. Total yield about 5oz
Third grow using mix of autos and feminised photoperiods, same soil and nutes but with
Bacillus thuringiensis to keep them under control and insect filters over fan intakes.
Chopped very early due to gnat larvae eating root systems on most seedlings before they could develop properly, remaining plants stunted and ended up infested with white creatures coming out of the soil. Ended up with only half oz.
Grow area was bleached and washed down carefully between grows to make sure no residual bugs left.
This is attempt 4 and using john innes garden centre soil instead of the bioterra. No bugs spotted so far but all plants have this weird leaf growth, some worse than others. Something interesting I noticed is house is a very old building, had the roof insulated after successful cfl grows but before the current run of failed hps grows and this has caused damp and mould problems on some walls and around windows etc. Since the house was insulated and damp problem was noticed the plant root systems have all been rather poor when checked after harvest and when repotting. Soil usually falls apart when repotting instead of being held together by nice tight root mass like it used to be. Plants also growing much slower than before building was insulated. Wondering if there could be any spores or nasties in the air caused by damp that are causing issues for the plants? Never had any rot or mould issues with the plants and buds themselves.
