Hi
well I just looked at the fox farm soil that u are using and I do not understand how this could have happen.. The few things that I am think- are u using a complete Micro Grow and Bloom feed and are u using a pH pen to adjust your mix? Fox farm is claiming they use an Organic soil mix; were as, I use a sterilized soilless mix. Your potting soil should be more well rounded than mine and would not require u mixing feed for a weeks MIN with your wattage used. This is why I am guess it is your pH.. U need to adjust your pH mix before feeding your plants.. I do not know if u mix your feed and than water your plants, but u need to mix your feed and than check pH- usually a little pH up will be needed.. That all depends on your tap water + season. I am sorry this is taking some time I might have been over looking the standard steps to growing-and since you are new, I should have condisderd that.. Anyways, some good news, your plants look bug free hehe and atleast they are growing..
I they are about week 2 in def and need attention. Vitamax and a balanced micro, grow, bloom will do it.. Thats all. What products are u using by your brand? I can take a peek and see if you are using a 3part or all in one, etc.. or two part such as Sensi grow and bloom.
Anyways, looks clean, I like it!!! Ill keep in touch on PMSG.
For some funny reason I am thinking you are testing pH of soil??
