hi people ive got five blues plants in soil under a 600 watt light ive had to go away for a few weeks and left a freind looking after my girls and hes cum into sum problems. first he let two of the plants get burned he said not to badly but i think hes trying to make me feel better lol now hes telling me that all the plants leafs have gone droopy and turning yellow this is my first grow so i dont have a clue all i have them on at the min is coco a and coco b if that makes sense ive been feeding them everyday 350 ml of water cud this just be there not getting enough water they are about 28 inch tall and very bushy any ideas wat cud be going on and plzs be gentle ps there about 3 weeks into flowering

Could be pH issue, nute burns, nute deficiencies, over/under watering, salt buildup. I really would need to see a picture for a diagnoses. However I like the motto, is if in doubt, flush.

Also I had a plant cap out at 39" and It would consume 5 liters of water a week.

thanks for the quick reply i cant put any pics up till saturday wen i get bc . ive just got him to have a look now so i can try exsplain the leaves all over are turning yellow i think this would mean a ph issue how do i sort that out but would this effect all 5 of them at the same time all the plants got the same syptoms the same day i thought first that they wasnt getting enough water they are very bushy as i said how much water are u meant to giv them and how often thanks

Its probly ph. Get use poland spring water. I give them water, once i can dig my finger about a inch into dirt and it dry, I water again. Then you will figure out how often and how much you will need after a few times. flush with some good water. If they are real tall and bushy like that you may have to water more then once a day depending on your pot size

thanks for the help ,there in big pots dnt quite no the size , ill try this and then get bc to u how long would it take to get sum improvement from them thamks
