GSC COCO 125W MARS HYDRO LED

12/4/19 Day 15. The darkness has spread further on GSC and started to appear on GG. So I think it could be a phosphorus deficiency or I have soaked them to much. Yesterdays feeding in a circle around the seedlings makes more sense then wetting everything. So both plants have had another 1L of feed 0.25ml coco a and 0.25ml coco b, 1ml cal mag and 1ml roots (ph 5.7 and EC 0.6). Did this around same circle as yesterday but today I got run off. GSC 300 ml run off PH6.4 EC1.8 GG 400 ml run off ph6.6 ec2.0 13/4/19 Day 16. Gave each plant a 1L feed of same solution as yesterday in a circle and got run off. Both plants seem to be doing better now I'm not soaking the whole pot. GSC 400ml run off PH6.4 EC1.6 GG 500ml run off PH6.7 EC1.5 14/4/19 Day 17. Gave each plant a 0.5L feed of 1/3ml/L coco a & b, 1/5ml/L roots, 1ml/L cal-mag. PH5.7 EC0.8 Again I fed in a circle around the seedlings. GSC 200ml run off PH6.6 EC1.4 GG 100ml run off PH6.8 EC1.5 15/4/19 Day 18. Gave both seedlings 1.5L feed same feed as yesterday, did this over the space of a few hours. GSC run off PH6.5 EC1.3 GG run off PH6.8 EC1.3 16/4/19 Day 19. Plants are both looking ok, no more signs of any deficiency's spreading to newer growth. Have lowered the light from 24inch to 21inch. I'm not going to feed the plants today. 18/4/19 Day 21. Week had flown by, still not fed the plants since the other day, the pots are heavy still. Both plants are looking happier now, they may be a little bit behind where they should be after 21 days but shit happens.
