Hello everyone, I am a first time grower and am facing some problems so I wanted to get some professional advise. I am currently growing in a city that does not have any head shops or nute shops. I went down to the local fertilizer and picked up a mix of 20-20-20 NPK and that's all I have been using. But I am starting to see some deficiencies in the plant an need some professional advice on how to deal with them. Your help will be extremely appreciated
they look pretty good. I don't see any deficiencies from the pics. those brown leaf tips maybe a little bit of Nute burn. Mj from someplace on something
In veg you don't need no 20-20-20, best is 20-10-10, and bud would be 10-20-20, see the difference, but getting a good tomato organic mix from your best local garden store is the way to go, later if you need to top up the nutes best is to foilar feed, or suffer the expected nute burn, and a serious learning curve Right now I'd flush with 3 times the volume of each pot with air temperate Ph neutral water, allow to recover overnite or 1x day in dim light, then continue,....no nutes for 2-3 weeks or until you see an active recovery. Cfl's still put out shit light, get your plants to within 2 inches or so of the tips, keep a temperature gauge in there and maintain 75f/25c at about 65%Rh
Their looking pretty good. Make sure no water drops are left on the leaves when your lights are on. Light refraction through water droplets will burn the leaves. The tips are showing signs of potassium deficiency. Your in flowering by the looks of it. Reduce your nitrogen, increase your phosphorous and potassium. If it has progressed, flush with plain water, wait 2-3 days, feed with minimal amounts of nutes. Find a food with an N-P-K of something like 5-30-20. Also, here is a chart to track future deficciencies.
Thanks for the advise guys. My question is however how am I in flowering the plants are only around 1.5 month old or 2. I have been giving them a constant 18 hours of light.
Oh so what do you recommend that I do? Is the yield going to be greatly affected? The plants are still pretty small in size.
if they are in fact autoflower, keep on same light schedule, do not top(again), and you will have a small yeild any way(if they ARE autos').
Ok.. So how can I tell if they are auto flowering and if they are should I change up the nutes? I have changed the aluminum with white paint covered walls and will flush them out with only water as advised earlier. Any other suggestions?

Did you start them from seed or where they clones? Do you know the strain? If from seed, did you buy them, have them given to you, find them in a bag of smoke you bought? I am only guessing that it is an auto from the way it looks. Small and flowering after only being 1 2/2 months old.
pics #2,3,4,7 all show 2 limbs branching off of the main stalk at about the 3rd node. This is usually an indicator of a plant being topped, the top growth cut off to force lower limbs out and up. If in fact it IS an auto, topping will slow growth and reduce yeild.
Hello everyone I'm on my second grow and I'm already facing a problem. I germinated the seeds put them in soil they sprouted and they've been stuck at the same size for the pas week. And a half. They haven't grown at all.. And now the cattldon a are yellowing off as are the leafs a little bit. Soil is a mix of Pete and perlite. I water with distiller water and have two 100 w fluorescent lights right over them.. Here are pics from a week ago. They still look the same but they are a bit more yellow now.. Please need some advice on how to salvage my babys Sent from my iPhone using Grasscity Forum
