Over/under Feeding or?

Hi,

So I am at 6 weeks veg using CFL's (6x23w) single plant of unknown strain. Watering is every 2 days (3 liters ph 7.4) or when the pot feels empty/dry. every other watering i feed it with 2 ml general organics bio thrive grow and 2 ml bio bizz heaven in that 3L water. so after adding the nutes ph drops to 5.5~ish. ph up'ed it to 6.8 and feeding as normal. Runoff ph is 6.8ish. Temps are at 86F. Used to be higher at 94 or 95F due to too many CFL's. (had 12x23w) Dropped to 6 and temps are ok now. Lights are on 24x7

Past week or so leaves started showing color changes. Is this over feeding or under? Cant be ph as i check it going in as well as coming out. Pics attached. Thinking of flowering in 10 days. Any help would be appreciated. Thanks

.

Edit:Notice the tips curling. I am guessing that was due to high temps which prompted me to reduce the no of cfl's.

Edit2: Oh and i had a ph issue earlier. runoff was 5.5 ish so i added some crushed garden lime and now runoff seems ok

Pot size is 5gallon. well it isnt exactly every 2 days. more like 2.5 days lol. If the pot feels light i water. Cant use MH/HPS due to heat issues. Underfeeding is ok. I can always give more. Was afraid I was over feeding. gave her 2ml +2ml (bio bizz heaven and go thrive) last night. will feed again tomorrow. Maybe i'll up it to 2.5ml + 2.5ml or 3ml + 3ml

Is it possible to over feed with organic nutes?

This is because of the Ph not being 6.5 and under watering.

Isnt ph in soil supposed to be between 6 and 7? and i dont think i am underwatering. But thanks for the input. will monitor for a few days and see whats up...

So it looks like my plant is recovering. Yay?!? Just out of curiosity what are these 2 thingamajiggy's sticking out of the nodes?

Edit: I am still in veg mode. 6 weeks and 3 days now since germination.

if you have corrected the ph your golden! I do believe you (were) overwatering because of the ph issue when a plant is stressed it will not use as much water now that she is back on track i would let her dry well then soak and repeat i would water her from the bottom of the pot. set her in a bucket of water for a few minutes let her get soaked when you pull her out you will get alot of run off which will help clean her out then let her dry this may take up to 4-5 days just let her dry well! i have done this from time to time never fails for me. lots of yellow comes out of the pot.

hmm, haven't tried the bottom watering trick yet but let me try it. When it comes to watering i usually water until i see a little bit of runoff about 5% of the total amount. And yea what ever the amount of runoff, its always yellow in color. Any suggestions on the biobizz product line to use here? Already i am using 2ml of bio heaven per feed. So any of the other one that can be beneficial? Also is possible to over do it (as in nute burn) using organic ferts like biobizz?

Also any idea what the 2 pokey things poking out of the plant at the nodes?
